2 Claims. 1

My present invention relates to a novel device for use, for example, inremoving the cover from a ar.

In spite of attempts made to provide a device that will enable jarcovers to be removed with less difilculty than is so commonlyexperienced, none has combined an inexpensive and rugged structure withease of its adjustment and use.

In accordance with my invention, I provide a device consisting of afirst member, the intermediate part of which is flat and which has atone end a first cover engaging element and at the other end a downturnedflange through which is threaded an adjustable element. I form a secondmember with a curved portion terminating in a second cover engagingelement, a flat portion, and a seat intermediate these portions disposedto be engaged by the adjustable element when the members are assembled.Preferably, the second member, except for its cover engaging element,has marginal stock disposed in the zone of the curved portion and theseat as an upstanding flange and in the zone of the flat portion toestablish a slideway receiving the flat portion of the first memberthereby to slidably interconnect the members so that as the adjustableelement is threaded into engagement with the seat, the clamping elementsare drawn towards each other. In practice, the flat and curved portionsof the second member are so disposed relative to each other that whenthe two members are assembled, the intermediate part of my device isspaced from the cover of the jar to which it is fitted to enable it tobe readily manually engaged with the folded marginal stock ensuring thata firm grip can be comfortably maintained.

In the accompanying drawings, I have shown an illustrative embodiment ofmy invention from which its novel features and advantages will bereadily apparent.

In the drawings:

Fig. 1 is a top plan view of my device applied to remove the cover froma jar.

Fig. 2 shows the device of Fig. 1 in side view, and

Fig. 3 is a section along the lines 3-3 of Fig. '1.

At 5, I have indicated a jar having a cover 6 which, even when tightlyseated thereon, may be readily removed by my jar opening device.

A device in accordance with my invention comprises first and secondmembers generally indicated at 1 and 8 respectively. The first member 1includes an intermediate flat portion 9 having a downturned flange ID atone end and its other end shaped to establish a first cover engaging element 1 i. The cover engaging element II is preferably in the form of awedge having a centrally disposed notch l2. Threaded through the flangel l is the adjusting element It.

The second member 8 consists of a curved portion It terminating in asecond cover engaging element [5 and a flat portion l6 separated fromeach other by the seat I! adapted to be engaged by the adjusting elementI3. In the embodiment of my invention shown in the drawings, the curvedportion 55 tapers inwardly towards the seat [1 so that the second coverengaging element I5 is of substantial size. Except for the element IS,the second member 8 has marginal stock which in the zone of the curvedportion l4 and the seat i! is disposed upwardly as at It and in the zoneof the flat portion I6 is disposed to establish a channel I9 slidablyreceiving the flat portion 9 of the first member 1 thereby to slidablyinterconnect the first and second members so that by advancing theadjusting element l3 into engagement with the seat H, the cover engagingelements H and I5 are drawn into clamping relation to the cover 6.

Preferably, the flat portion I6 is disposed relative to the curvedportion l4 so that when assembled and clamped in position, theintermediate part of the device is spaced from the cover 6 so that itmay be firmly grasped by the hand of the user. When thus held, themarginal stock ensures that a firm grip may be comfortably maintained.

From the foregoing, it will be apparent that my invention provides a jaropening device of simple and inexpensive construction that is easilyadjusted and operated to remove the cover from its jar.

What I therefore claim and desire to secure by Letters Patent is:

1. A device for use in removing the cover from a jar, said devicecomprising a first member including at one end a first cover engagingelement and at its other end a downturned flange, an adjustable elementthreaded through said flange, and a second member including at one end aslideway slidably connecting the intermediate portion or" said firstmember thereto, a second cover engaging element at its other end, and anintermediate seat engageable by said threaded element as it is rotatedto draw said clamping elements towards each other, the portion of saidsecond member between said seat and said second element defining withsaid intermediate portion of said first member such an obtuse angle thatthe intermediate part of said device is spaced sufiiciently above acover engaged by said elements to establish said part as a hand grip.

2. A device for use in removing the cover from a jar, said devicecomprising a first member including a fiat intermediate portion, a firstcover e gaging element at one end and a downturned ange at its otherend, an adjustable element tkreaded through said flange, and a secondmemb r including a curved portion terminating in a second cover engagingelement, a flat portion and an intermediate portion establishing a seatengageable by said adjustable element, both of said portions includingmarginal stock, the marginal flanges of said curved portion extendingupwardly and the marginal stock of the fiat REFERENCES CITED Thefollowing references are of record in the file of this patent:
